BED-BOTTOM.

Specification forming part of Letters Patent No. 50,168, dated September 26, 1865.

To all whom t may concern:

Be it known that I, RUEUs S. SANBORN, of Ripon, in the county of Fond du Lac and State of Wisconsin, have invented an Improved Suspension Spring Bed-Bottoni; and I do hereby declare the following to be a full and correct description ot the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view of a bedstead with one ot' my spring-bottoms attached, part of the foot-board and side rail being removed to show more clearly the mode of attaching the springs and slats. Fig. 2 is a transverse vertical section of the bedstead and bottom. Fig. 3 is an enlarged detail View, showing the mode of supporting the springs and the mode of attaching the rails to the springs. Fig. 4 is an enlarged detail view, showing the Inode of attachment of the transverse rail.

The same part is marked by the same letter of reference wherever it occurs.

. The nature of my invention consists in forming an elastic bed-bottom by suspending elastic slats by rubber springs at their ends to the bedstead-frame, said slats boing supported, if necessary, by one or moretransverse slats also suspended by rubber springs to the frame of the bedstead, all as hereinafter more particu larly set forth.

To enable others to make my improved bedbottom7 I will proceed more minntely to dcscribe its construction, referring to the drawings, Whereon- A marks the head of a bedstead, and B the foot; C, the sidel rails; D, the longitudinal elastic slats forming the bottom. The elasticity of these slats can be 'modified at pleasure, according to the character and thickness of the wood of which they may be made.

E is a transverse strip or fillet which secures the rubber springs in place, it being screwed to the head o1 foot of the bedstead for that purpose. It has grooves a on its inner face for the reception of the springs, as clearly shown in Fig. 3. The springs F are of rubber, and I prefer to make them of annular form or oval, so as to present. loops below the strip E for the reception of the ends of the slats D, which have notches b in them to receive the springs.

Below the longitudinal slats D, and near the middle of their length, I place one or more transverse slats to support the slats D at their weakest point and the point at which the great-- est Weight has usually to be supported. But one ot1 these transverse slats G is represented inthe drawings. Its ends are supported by annular rubber springs in the saine manner as the longitudinal slats, the springs being fastened to the side rails by the blocks H, which are screwed to those rails.

Fig. 4 clearly illustrates the mode of attaching the transverse rail and its springs.

This mode of construction,with the obvious modilications in the size and number of the slats and springs,is applicable to sofa-bottoms and other similar purposes.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination ot' longitudinal and transverse Wooden slats D and Gr, suspended from the frame by annular rubber springs which are attached to notched strips E and H, substantially in the manner described.

The above specification of my said invention RUFUS S. SANBORN.
